Subject: usbip: vhci-hcd: Add USB3 SuperSpeed support
From: Yuyang Du <yuyang.du@intel.com>
commit 1c9de5bf428612458427943b724bea51abde520a upstream.
This patch adds a USB3 HCD to an existing USB2 HCD and provides
the support of SuperSpeed, in case the device can only be enumerated
with SuperSpeed.
The bulk of the added code in usb3_bos_desc and hub_control to support
SuperSpeed is borrowed from the commit 1cd8fd2887e162ad ("usb: gadget:
dummy_hcd: add SuperSpeed support").
With this patch, each vhci will have VHCI_HC_PORTS HighSpeed ports
and VHCI_HC_PORTS SuperSpeed ports.
